Parallel circuit resistor requirements

Post by Matty1973 »

Help please!!

So I am always learning and my circuitry skills are getting better but I need help with this

I am lighting a NX01 kit and I have the prebuilt circuits for the strobes but I want to make the circuit for the illumination LEDs

I have an old torch chip that caters for 24 LEDs to be attached in parallel with 1 resistor after the positive terminal,

What I want to know is if instead of having the 1 single resistor can I just wire up all LEDs to the board and then each led has it's own resistor?

Yep - though I'd watch to see what resistor value it is

If it's a higher value, that means that more power (volts & current) are being "stopped" by it - and that also means more heat dissipation

One resistor dissipating a fair amount isn't going to heat up much - 24 resistors dissipating the same amount may generate enough heat to damage styrene

In a parallel circuit, 1 or 24 - each one will still have the same value ergo the same power/heat dissipation
